Besides Masterofthehorse, who do Ballydoyle have for the Leger? Age of Acquarius, Freemantle and Black Bear Island are not good enough on all known evidence, and I don't think Golden Sword will stay.
They'll have a double handful they will be thinking about by Sadler's Wells, Galileo, Montjeu, etc. Other yards don't have this sort of strength in depth in the staying ranks. Some of these are yet to be fully shown off.
